These include a range of formulations for thermionic and field effect surface emission, secondary emission from surfaces and from within volumes, and magnetized plasma emission the last of these being a specialized plasma emission module designed for the efficient analysis of magnetron sputter coating systems.
The hyperopic shift in refraction observed in ketamineâxylazine-anesthetized mice theoretically may be caused by either reduction in the axial length of the eye or changes in the refractive indices of the ocular media.
Hyperopia develops in eyes that focus images behind the retina instead of on the retina, which can result in blurred vision. This occurs when the eyeball is too short, which prevents incoming light from focusing directly on the retina. It may also be caused by an abnormal shape of the cornea or lens.
